T0 all whom it may concern .i

Be it known that I,

Hoboken, in the .county of Hudson and State of New Jersey, have inventedcerta-1n new and useful Improvements in Fountaln- Pens, of which thefollowing is a 'speclication.

struct a fountain three tubes of suitable material in which the innertube acts as a protection to the elastic sack, into which is sucked bycompressing said sack by air pressure, produced by drawing the innersliding tube out, letting air into the tube through an opening in thetop of the said tube and then placing the finger over the opening toretain the air and pressing the same back to its normal position an thuscompressing the sack alongA its whole length thus forcing the air or inkthat may be contained .in the sack out. The pen nozzle is then insertedinto the ink, the opening at the other end released, and the vacuum sackis iilled Awith ink. The interior tube is provided at its outer upperend, wlth a shoulder, which engages with the shoulder provided on thelower inner end of the middle or compression tube, and is thus preventedfrom being pulled entlrely off the innermost tube. Furthermore, theshoulders on the two inner tubes act as a packing to prevent the airpressure being partly' lost, s1nce they form a practically air tlghtcompartment, so long as the end opening is covered.

Another object I have in view, is so compressin .the sack, that it willnot collapse, and wi carry suicient ink to fill the entire length of thebe. l

plungers and other de vices have been tried but in suchcases the sizeand cannot carry sufficient ink, the sack in many cases buckling, thuspreventing the inlet of ink in suicient quantity.

I attain these objects by' means of the mechanism shown on, theaccompanying drawings, in whichl Figure 1, is a vertical sectional viewofA a fountain pen embodying the chief particulars of my invention. Fig.2, is a vertical sectional view, with the central tube drawnSpecification of Letters Patent. nppncationmed March 2s, 1914. serialN0. 827,806.

Flg. 4, isa vertical sectional' view show-` 4 is a shoulder which tstightly into the Y,

forward end of an inner tube 7, the forward end of the said inner tubebeing forced into the recess 3 between said shoulder 4 and the threadedend of the nozzle in order to make a tight j0int;'5 is a shouldernarrower at its base, in order to form a collar to which thesack 6 istightlypfixed by any -suitable means.

7 is the inner tube having at its rear end the shoulder 7*". A y 8 isthe outer casing or tube, which may be constructed of hard rubber or anysuitable material andis provided at one end on side with a thread 13 to`lock the same with the noz'zlethread 2.

9 is a cap showing a centralair is drawn for the purpose of compressingthe sack to charge the same with ink. -This cap maybe attached to thetube 7 by friction and may be of sulcient length to serve as a cap forthe nozzle and pen although` the cap 9 being conically shaped, may serveas a holder for a protecting cap for the nozzle, but not here shown. 'g

10 are the air openings;

11 is a space formed between the inner and outer tubes, in -which thepacking 7a slides. Of course these will be tted to allow the tube 7 tobe forced down, without too much resistance; 12 is the sack 6,

the nozzle 1. l

To fill the pen it is only necessary to draw out the tube '7, by meansof the cap 10.

Then the vfinger is Pressed' over the opening and the tubes 7 ispacln'ngs 7 and 7 a shown 1n a compressed form,v 'brought about by thepressure of the air orced back to its normal 11,0
